Tissue evolution: Mechanical interplay of adhesion, pressure, and heterogeneity [PDF]
New J. Phys. 22, 033048 (2020), 2019 The evolution of various competing cell types in tissues, and the resulting persistent tissue population, is studied numerically and analytically in a particle-based model of active tissues. Mutations change the properties of cells in various ways, including their mechanical properties.

Tissue adhesives and sealants [PDF]
Aesthetic Surgery Journal, 2003 Rapid and secure tissue adherence using adhesives or sealants is an attractive concept. Cyanoacrylates, marine adhesive proteins, fibrin-based sealants, and mixtures of polypeptides and proteoglycans to form "laser solders" are just some of the products and technologies that have been used.

Biomimetics, 2023 The occurrence of leakage from anastomotic sites is a significant issue given its potential undesirable complications. The management of anastomotic leakage after gastrointestinal surgery is particularly crucial because it is directly associated with ...

Solid-state inorganic and metallic adhesives for soft biological tissues
Japanese Dental Science Review, 2023 Currently, the soft-tissue adhesives used in clinical practice are glue-type organic adhesives. However, there is a demand for new types of adhesives, because the current organic adhesives present challenges in terms of their biocompatibility and ...

In-vitro evaluation of antibacterial potential of cyanoacrylate tissue adhesives for intraoral wound closure [PDF]
Journal of Dental Materials and Techniques, 2017 Background: Cyanoacrylate tissue adhesives have been used as a substitute to silk for intraoral wound closure. Placement of sutures provides a corridor for accumulation of microorganisms into tissue which leads to infection. Cyanoacrylate-based adhesives

Effect of adhesion geometry and rigidity on cellular force distributions [PDF]
Phys Rev Lett 103, 048101 (2009), 2009 The behaviour and fate of tissue cells is controlled by the rigidity and geometry of their adhesive environment, possibly through forces localized to sites of adhesion. We introduce a mechanical model that predicts cellular force distributions for cells adhering to adhesive patterns with different geometries and rigidities.

Treating Facial Cuts to a Near Scar Less Outcome in Children
Journal of Nobel Medical College, 2021 Background: Facial Lacerations constitute an important reason for children (< 18 years) to visit emergency room. While bleeding and pain are the associated acute problems, the long term outcome in terms of a cosmetically acceptable scar is a matter of ...

Adhesion as a trigger of droplet polarization in flowing emulsions [PDF]
arXiv, 2021 Tissues are subjected to large external forces and undergo global deformations during morphogenesis. We use synthetic analogues of tissues to study the impact of cell-cell adhesion on the response of cohesive cellular assemblies under such stresses. In particular, we use biomimetic emulsions in which the droplets are functionalized in order to exhibit ...

Growth and shrinkage of tissue sheets on substrates: buds, buckles, and pores [PDF]
New J. Phys. 26, 103027 (2024)Many tissues take the form of thin sheets, being only a single cell thick, but millions of cells wide. These tissue sheets can bend and buckle in the third dimension. In this work, we investigated the growth and shrinkage of suspended and supported tissue sheets using particle-based simulations.

Cadherin-Based Intercellular Adhesions Organize Epithelial Cell-Matrix Traction Forces [PDF]
, 2012 Cell--cell and cell-matrix adhesions play essential roles in the function of tissues. There is growing evidence for the importance of crosstalk between these two adhesion types, yet little is known about the impact of these interactions on the mechanical coupling of cells to the extracellular-matrix (ECM).
